Opening of valv; :tadrt atmosphefic air fj the? incu bation In order to provide jinterior of the chamber by means ;of extensions "59 which extend along the -bottomcof the chamber at' each side and are provided fresh heated air through the chamber ?I pro vide an air passageway 38'eXtending from the chamberto the air intake 24 tothe'burner. This air passageway communicatesfwith the i with a plurality of, air intake' openings .41:.

By this means I draw-air from the bottom 'of 'the chamber to"feedfthe' 'burner and the the" rate of J withdrawal by i regulating i the rate of' combustion in' theburner' j' Their-esh heated air entering the 'chzumber at the top lis drawn' therethrough over the 'eggs disposed therein and out of the chamber atthe bottom', and; a. steady circulation' of. r freshheatedaris maintained throughout r the ineubation'bh'amber over the jeggs; The

The corridor is PVded with a :ceiling I 4:4' 'supported' from *the ceili'ng of 'the' incubation chamb er by bra'clets 46 and has a floor 4:7 carried by supports 49. Curtains 48 hang fromthe ceiling at eaoh side. The walls--of the incubation chamber are o.f;-'suitable materialto preserve the temperature' within the chamber; v

have described in( my :co-,pending appli-` Cation above njotecl my improved process of eggincubation andthe operation' of'the A apparatus used in its accomplishmentand 'supports '52. ;Thesh'aft carries aplurality of rotatable drumsOa. I have shown these for a circulation of 7 drums 'as adapted for independeit rotation andcapable of *being independently locked at difierentpoints in their 'rotation. i i

InFgj I haveillustrated one of these i members '60. These rim members are sup: portedfrom the hubby a plurality ,of pairs of radially extendiiig spokes 61. 'These gspokes are provided with flanges '64 whichserve as supports for'removabletrays p i s Ir Figs. eand 'lshw single tray'with" air' is drawn therefrom in response` to the requirements ofthe burner, and I regulate its provided removable cover( Each tray is in' the form ofa sector ;ot` the drum. The

the tray t has i side walls 'which eirten d from' the end 68 to' asmallz. arcuate endpor tionf7 'whioh'is 'adaptedto' -abut the 'hub 58 of the idrum. I The'tray is provided with a screen mesh `bottom"72""and ?a removab detachably pivotally connected' with ;the tray* by means, of hinges 76; -"-'I `he s`e 'hingesgcom prise detachable sectionsso as topermt com plete removal of the cover' from the tray; A catch`78 is provided bym'ans of which the cover maybe'fasteried to the tray.

The tray isfilled with' eggs standing. on end' between the'scr'een i 'cover and the 'screen bottom. The' tray is then insertedjin the' drum between successive pairs of the radiallyextending tray supports; I have provided a pin 80 Secured; to the drum byacord-81 which pin 'is adapted to extei'd 'through an' aperture'83 inthe rim' of the drum outside" of the end ofthe tray to holdthe tray I place-'in the'drum; In the' working out of my process such ;number of trays or 'drums' as is desired may be'filled with'eggsf*"'*` i It isnecessary to turn; th" eggs fromtime to time and this is accom'plished by rotating the drum upon the shaft 50. f The eggs should be a turned from one ,side to a the other and' I; therefore, have provided -means; to asten the drum againstrotation afterit has been rotatedthrough anare of 180 jdegrees.

t A bar 82 extends longitudinally of the incubavals. ,These catches are ajdapted to bemoved into recesses 8 5 formed inthe drum rim't ure the drum against rotaton.

When the eggs are placed.
